Genetic Testing for breeding

Genetic Testing

These are known problems in Shih Tzu, however, no genetic testing is available for umbilical hernia, inguinal hernia, portal systemic shunt (PSS), and autoimmune hemolytic anemia. It is strongly recommended that testing be done before you even consider using your Shih Tzu for breeding. Consultation with your veterinarian is also recommended.

Text is from American Shih Tzu club

It`s very good that breeders test there dogs... but in Europe a lot of breeders don`t have to.. only in America you see this a lot.
Is it because in America there are more shih tzu`s with health problems?? Or are the numbers the same... and in Europe we just don`t know it because we don`t test our dogs.

in Lithuania we need to do for shih tzu eye test and Hip dysplasia(I'm not sure is it this, but they cxheking the legs )
without ths we can't breed our dogs...

I think you mayby meen Patella Luxatie... don`t know if this is the correct way to say it in englisch.

It would be a good thing if any test would be done in the Netherlands and other country`s to.

No, it`s another test for dogs, shih tzu don`t need it, shih tzu need a kneecap testing, it calls Patella luxation.

I think this test is very important for breeding healthy dogs, there are many small breed dogs with such a problem. There are plenty of for example yorkies in Lithuania, who cannot be bred because of this problem. Earlier, when this test was optional, we didn`t see that problem...
